Pages and Containers
There are two main concepts in Zend\Navigation:
Pages
A page (Zend\Navigation\AbstractPage) in Zend\Navigation – in its most basic form – is an object that
holds a pointer to a web page. In addition to the pointer itself, the page object contains a number of other
properties that are typically relevant for navigation, such as label, title, etc.
Read more about pages in the pages section.
Containers
A navigation container (Zend\Navigation\AbstractContainer) is a container class for pages. It has methods
for adding, retrieving, deleting and iterating pages. It implements the SPL interfaces RecursiveIterator
and Countable, and can thus be iterated with SPL iterators such as RecursiveIteratorIterator.
Read more about containers in the containers section.
Note
Zend\Navigation\AbstractPage extends Zend\Navigation\AbstractContainer, which means that a page
can have sub pages.
View Helpers
Separation of data (model) and rendering (view)
Classes in the Zend\Navigation namespace do not deal with rendering of navigational elements. Rendering is done
with navigational view helpers. However, pages contain information that is used by view helpers when rendering,
such as; label, class (CSS), title, lastmod and priority properties for sitemaps, etc.
Read more about rendering navigational elements in the view helpers
section.
